Search reports

search_reports
Read-onlyIdempotent

Find relevant bug reports by describing the issue in plain text; get ranked results with summaries and similarity scores.

Instructions

Search reports by meaning and keyword (pgvector similarity server-side; falls back to summary/description substring if embeddings are unavailable). Returns ranked { results: [{ id, summary, similarity }] }. Read-only. Use to find reports by free text ("checkout flakiness"); use get_similar_bugs to dedupe a known component/bug, or get_recent_reports to list without a query.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

  "method": "tools/call",
  "params": {
    "arguments": {
      "query": "<query>"
    },
    "name": "search_reports"
  }

TDQS

A4.5/5.0
Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover read-only/idempotent hints. The description adds real behavioral context beyond those: server-side pgvector similarity, a fallback to summary/description substring matching when embeddings are unavailable, and the ranked result shape. This is more than minimal, though it does not discuss rate limits or auth—minor given the tool's read-only nature.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tightly constructed sentences front-load the mechanism and result format, then move to usage guidance. Every sentence earns its place; there is no filler or redundancy.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With a full output schema and 100% parameter schema coverage, the description still adds the essential behavioral twist (fallback) and explicit sibling routing. Nothing an agent needs to correctly invoke this tool is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, and the schema already documents query, limit, and threshold including defaults. The description reinforces that the query is free text or component path but adds no new parameter-specific detail beyond the schema, so the baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource ('Search reports by meaning and keyword') and explicitly names sibling tools (get_similar_bugs, get_recent_reports) with contrasting use cases. An agent can immediately distinguish this from related search/list tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit when-to-use guidance ('Use to find reports by free text') and when-to-use-alternatives guidance ('use get_similar_bugs to dedupe a known component/bug, or get_recent_reports to list without a query'). This fully answers the routing question.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
